Day-to-day team: Josh (CTO), Michael (CEO) and you
You'll be kaizen's first dedicated engineering hire, driving the technical direction and delivery of the product across our React Native app and Python/AWS backend. You'll work alongside Josh and Michael on product decisions while taking increasing ownership of the application, infrastructure and release process as Josh focuses more deeply on our sports science and training models.
This is for someone who can make major architectural decisions, cares about the implementation details and has a nose for the work that will have the biggest impact.
kaizen is a load-based running training app used by more than 50,000 runners. We're live on iOS and Android, have paying subscribers and generate five-figure monthly recurring revenue. We've recently raised a pre-seed round to accelerate our progress.
Josh originally built kaizen for his own training. Michael joined as cofounder to turn it into a company. Our ambition is to build the running platform committed runners use every day.
Our next challenge is turning kaizen from a single-player training product into a platform capable of supporting different training systems, athlete-led training experiences and deeply personalised guidance— built on a runner's complete training history.
That creates substantial technical problems across historical data ingestion, wearable integrations, personalisation, training models, reliability and performance. kaizen already supports everyone from Olympians to runners completing a marathon in more than six hours.
You'll build and ship alongside Josh while taking increasing ownership of the application stack, infrastructure and release process. You'll have strong, grounded opinions and help drive decisions about why, what and how we build.
